spying on your kids is sometimes necessary but most of the times not..expeually if you know them well. the "RIGHT" to spy on your kids is necessary to keep them safe and let them explore and learn on their own. but it also makes them feel usurped from their own choices. like my parents don't trust me so they watch everything i do they say what to do and when to do it and how to do the thing the parents said the kid to do the thing the parents chose to have the kid do. My parents trust me but they still keep an eye on me.(sometimes two eyes.) but they also realize that I'm becoming an adult and need to be set free...though they will always keep an eye on me, because they love me and don't want me to mess up my life by doing something stupid.
